I've seen a few Sportcoaches in our 100,000 miles of travel in our 5 years, but honestly, I've seen more on the dealer lots than actually on the road, or in rv parks, etc... I believe they are good coaches, built along side the Mirada Select Class A gas, and others at the Coachmen facility in Middlebury, IN (building 1310), as I've delivered several Miradas to dealers across the country, but no Sportcoaches.
The Sportscoach is the 'diesel' line for Coachmen, though I don't believe they have a big market for them, and don't produce too many - the Class A Gas units get much more attention.
You may able to track down a Coachmen specific forum, or even a Sportscoach chat room, or similar, but even on these forums, we don't hear from too many of them.
